    Abstract: Liquid aspirator for drawing off and sucking up liquids, having a drawing-off lip, having a suction device for sucking up the liquid into a separating space in the housing of the liquid aspirator, having an exhaust-air channel, which is subjected to a negative suction pressure and is intended for leading the air out of the separating space, having a separating device, which is arranged in the separating space and separates the liquid from the water, and having a tank for accommodating the liquid. Complex guidance of the liquid/air stream is avoided in that the housing has a hollow chamber which forms the separating space and the tank, and into which the intake channel opens and from which the exhaust-air channel is guided out of the housing; wherein the hollow chamber contains a motor-driven rotor with a rotating impact surface, and the intake channel is designed such that the air/liquid stream is directed for radial direction reversal and acceleration onto the impact surface.

    Abstract: A hand held battery operated device for removing ice from glass window surfaces includes hollow handle and barrel portions. A motor within the barrel portion drives an activation shaft to produce reciprocative movement of controlled rate and stroke length. A scraper component, releasibly attached to the activation shaft exteriorly of the barrel portion, terminates in a straight edge adapted to apply impact force to the ice/glass interface.

    Abstract: A window scraper and method are provided wherein a scraping brush has filaments and wherein the tips of the filaments are moved linearly across the work surface as the brush rotates. Preferably, the brush has brass filaments trimmed to a point, and the brush drive mechanism moves the brush in an oscillating arcuate path while cams and cam surfaces simultaneously cause the brush to move toward and away from the work surface to maintain the tip of the filaments in substantially the same plane at a constant distance and pressure relative to the work surface. A novel brush has filaments trimmed to a point, an axle of rotation and cams to engage cam surfaces. The device includes an oscillating drive mechanism, a slot to rotatably and slidingly receive the brush axle, and cam surfaces to engage the brush cams and cause the brush axle to slide in the slot, causing the brush to move toward and away from the work surface during portions of the rotating brush sweep.

    Abstract: A MOTOR DRIVEN CLEANSING MACHINE HAVING AN ENDLESS BELT DRIVEN OVER A PLURALITY OF ROLLERS. ONE ROLLER FORMS THE FRONT EDGE OF A BELT-SUPPORTING MEMBER, BETWEEN TWO CONVERGING BELT-SUPPORTING SIDES, WHICH IS PIVOTABLY MOUNTED IN A FRAME. THE PIVOT AXIS IS PARALLEL WITH THE AXES OF THE ROLLERS. THE BELT-SUPPORTING MEMBER IS HELD IN A NEUTRAL POSITION BY THE TENSION OF THE BELT BUT IS PIVOTABLE IN EITHER DIRECTION WHEN THE FRONT EDGE OF THE BEL-SUPPORTING MEMBER IS PRESSED AGAINST A SURFACE TO BE CLEANSED.
